Abstract: Plural receiving recesses are radially formed at the periphery of the disc-like rotating body. The rotating body is rotatably installed at the base, and the cylindrical cover is provided at outside of the periphery of the rotating body. From the receiving region of the receiving recess for receiving the waterproof seal to downstream side of the rotational direction of the rotating body, the first brush and the second brush are attached with the cover and at the further downstream side, the detection device and the take-out device are mounted on the base in order.

Abstract: The present invention provides an oscillation measuring method comprising: a laser beam emission step S1 for emitting a laser beam to an object to be measured; a return beam reception step S2 for receiving a return beam reflected by the object and having an object Doppler frequency according to a velocity of the object; a self-mixing step S3 for mixing the return beam having the Doppler frequency with another beam emitted upon reception of the return beam and generating a self-frequency according to a resonator change during a time from the emission to the reception of the return beam, so as to generate a beat wave containing the object Doppler frequency superposed with the self-frequency; and an oscillation information output step S4 for outputting the beat wave or information obtained from signal processing of the beat wave as the object oscillation information. This enables to measure a fine oscillation of an object to be measured.

Abstract: A game providing method dispenses a golf ball that has an ID number recorded. A plurality of players hits the golf ball in turn from respective bays toward a fixed target position. A number of the golf balls hit from each of the bays is counted by counting means until an ID number recognizing device disposed at the target position recognizes a golf ball having an ID number corresponding to each of the bays. The number of the golf balls counted in each of the bays is displayed by display means.

Abstract: This application is an invention relating to an improvement in a gas burner for a stove for leading a mixed gas to flame holes, and burning the gas therein, through a gas passage (18) from a mixing tube (5) which produces the mixed gas by mixing a gas introduced in a jet from a nozzle and primary air drawn in with introduction of the gas. A sub-chamber (Ca) is provided separately from the gas passage for storing the mixed gas in a state of flux. The sub-chamber (Ca) communicates with the gas passage (18) through an inlet (3), and discharges the mixed gas stored therein through outlets (2) disposed adjacent the flame holes. With this construction, even when a continued combustion in the flame holes becomes difficult due to air-rich air resulting from an operation of an adjusting lever of the gas burner for a stove to adjusts the quantity of gas rapidly from large to small, the mixed gas stored in the sub-chamber (Ca) is discharged from the outlets (2) to continue the combustion.
